Zombie Make Up

As soon as I saw this piece of artwork [link] I knew I wanted to replicate the make up, and I finally got the chance since I've been off work with laryngitis
I was going back and forth about whether to make the staples etc more real looking, but I ended up just deciding to keep it like the picture

All credit goes to "Hilary Jane - www . tainted-orchid . deviantart . com" for creating such amazing art!
